CHAPTER V Carbonic rock rock sediment composition with

CHAPTER V. Carbonic rock: rock sediment composition with the dominant (> 50%) consists of MINERALcarbonic. Establishment PROCESS HAPPENS TO THE INSITU solution comes from EXPERIENCE THE PROCESS CHEMICAL OR WHERE biochemistry of organisms partake, CAN Happen grain ROMBAKAN OF THE EXPERIENCE OF MECHANICAL AND TRANSPORTATION DIENDAPKAN elsewhere. ENTIRE PROCESS IS held at SEA WATER ENVIRONMENT, SO Practical DETRITUS ASAL FREE OF LAND

Carbonate Rock Classification q Clastic Lime Stone: Lime Stone that detritus from settling back Lime stone home. Example: kalsirudit: grain size rudit (granule). Kalkarenit: arenit grain size (sand) Kalsilutit: lutit grain size (clay) q non klastik Lime stone: form of the process - a process chemical and organic. Minerals are generally mono. Can be distinguished: Biochemistry results: bioherm, biostrom. Results solvent chemistry: travertin, tufa. Results replasement: batugamping phosphate, dolomite Lime Stone

PEMERIAN CLASTIC LIME STONE Sistematika diskripsi the same with rock bottom sediments klastik: namely include texture, structure and mineral composition. 1. Texture: the same as the rock klastik sediments, only the term is only: Nama butir Besar butir (mm) Rudite Arenit Lutite >1 1 – 0, 062 < 0, 062 2. Structure: pemeriannya with the same sediments klastik 3. Composition: there also fragments pemerian, Metric, cement is only the term only.

CARBONATE 1. Allochem: fragment is composed by a framework or grain-grain klastik abrasion results from the previous batugamping there. Miscellaneous allochem: � Framework organisms (skeletal): a fragment consisting of the body shell, or animal body shell or framework of growth. � Interclast; is a fragment consisting of particle-particle abrasion of batugamping that previously have. � Pisolit: the grain-grain oolit with size> 2 mm. � Pellet: a fragment that resembles oolit but not danya showed concentric structure. 2. Mikrit: a fine aggregate 1 -4 micron-sized, crystals are made of carbonic biochemistry or chemical peripitasi directly from sea water and fill the cavity between the grains. 3. Sparit: is the cement that fill the space between the grains and rekahan, sized grains (0, 02 -0, 1 mm), can directly from the sediments of insitu or rekristali mikrit.
